To all whom it may concern Be it known that I, VILLTADI A. Smnnnr, citizen ofthe United States, residin at La ii-rang ge, in the county of Cook and btate of Illinois, have invented a certain new and useful Improvement in Water Heaters, of which the following is a full, clear; concise, and exact description.

Myinvention relates to water heaters and resides in the employment" of water conveying piping arranged substantially in the form of at least two connected rings which are provided with fuel burners beneaththe same and positioned to present their flames to the inner sidesof the rings; The pipe of one of these rings desirably has its ends facing in the same direction. 'The otherring is preferably formed of'two arcuate pipes each having its ends extending in opposite directions, each end of the first pipe being aligned with oneend of one of the s'econdaforesaid pipes. The rings are joined by two connecting pipes each in threaded connection with two of the aforesaid aligned pipe ends. The rings of pipe are desirably formed with inwardly projecting fingers that overlie the burners and which serve to support utensils upon the rings within heating range of the flames of the burners. Thereis also preferably employed an enclosing frame and lugs upon the outer sides ofthe rings and resting upon the frame whereby the rings may be separated'from the burners.

I will explain my invention more fully by reference to the accompanying drawing showing the preferred embodiment thereof and in which Fig. 1 is a plan view, partially in section, illustrating the water heater of my invention; Fig. 2 is a perspective view showing, somewhat diagrammatically, the rings included in'a water heating system; and Fig. 3 is a sectional view on line 33 of Fig. 1.

Like parts are indicated bysimilar characters of reference throughout the different figures. p

The heater shown includes an arcuate water conveying pipe 1 which may be a casting, there being illustrated a plug 2 through which the core sand may be discharged after the casting operation. The ends 3 and 4 of the water conveying pipe are preferably joined by a solid bridge piece 5 which maintains the pipe ends 3 and 4 in rigid relation without establishing water conveying connection therebetween. The ends 8 and 9 'of 1921. Serial No. 450,452.

each of the arcuate pipes 6" and 7 extend in opposite directions, each end ofthe first pipe 1 being aligned with one end of one of thesec- 0nd aforesaid pipes 6 and '7. Two connecting pipes 10 are each in threaded connection with two of the aforesaid aligned pipe ends, 3 and 8, l and 9.. uel burners 11, adapted to burn either gaseous or liquid fuel, are located centrally beneath the rings'l and 6,, '2". As illustrated, these burners are adapted to burn gas conveyed thereto through the pipe 12 which is provided withgas valves 13 each individual to a burner. Aframe l4 encloses the water conveying rings and the burners beneath the same, andsupports the gas pipe 12 and the valves 13 thatpertain'to the burners. Supporting lugs are Carried upon the outer sides of the water conveying rings, each of these lugs being desirably formed'in twoparts,.one part l5being rigidly connected with the corresponding ring and the other part 16 being-adjustably connected with the part 15 to varythe extent to which it may project from the ring. Adjusting screws 17 hold the parts 15 and 16 in selected adjustment, being suited to the width of the frame 14 upon which the lug elements 16 are rested to support the water conveying rings in proper relation to the burners that are beneaththem. Each of the rings is desirably formed with inwardly projecting fingers '18 which serve to support cooking utensils within proper distance of the burners.

The rings may be connected in any suit able form of water circulating system In Fig. 2 the rings are shown, diagrammatically, as being connected with a water tank 19 to which water that is to be heated may be fed from any suitable source of supply to a supply pipe 20 that is opened and closed by a valve 21, a water gage 22 indicating the level of the water within the tank. The cold water flows from the tank and is returned, heated, to the tank through piping 23 having connections that unite the endsS of the arcuate pipes 6 and 7 with the tank.

In the preferred embodiment of the invention the pipe sections ('3 and 7 are separately formed and are separately assembled with the pipes 10, an arrangement that enables me to employ right-handed threads upon the ends of the pipe sections 1O and correspondingly directed threads upon the aligned pipe ends that these pipe sections,

6 and 7 may be united at their ends 9 by means of a binding plate 24: bolted thereto.

-While I have herein shown'and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. In a water heater, the combination with an arcuate water conveying pipe whose ends face in the same direction; of two additional arcuate pipes with the ends of each extending in opposite directions, each end of the first aforesaid pipe being aligned with one end of one of the second aforesaid pipes; two connecting pipes each in threaded connection with two of the aforesaid aligned pipe ends; a fuel burner beneath the first pipe; a fuel burner beneath the remaining two pipes, said fuel burners being positioned to present their flames to the inner sides of said pipes; inwardly projecting fingers upon said pipes for supporting utensils; an en closing frame; and lugs upon the outer sides of said pipes and resting upon said frame. e I

2, In a water heater, the combination with an arcuate water conveying pipe whose ends face in the same direction; of two additional arcuate pipes with the ends of each extending in opposite directions, each end of the first aforesaid pipe-being aligned with one end of one of the second aforesaid pipes; two connecting pipeseach in threaded connection with two of the aforesaid aligned pipe ends; a fuel burner beneath the first pipe; a fuel burner beneath the remaining two pipes, said fuel burners being positioned to present their flames to the inner sides of said pipes; an enclosing frame; and lugs upon the outer sides of said pipes and resting upon said frame.

3. In a water heater, the combination with an arcuate water conveying pipe whose ends face in the same direction; of two additional arcuate pipes with the ends of each extending in opposite directions, each end of the first aforesaid pipe being aligned with one end of one of the second aforesaid pipes; two connecting pipes each in threaded connection with two of the aforesaid aligned pipe ends; a fuel burner beneath the first pipe; a fuel burner beneath theremaining two pipes, said fuel burners being positioned topresent their flames to the inner sides of said pipes; and inwardly projecting fingers upon said pipes for supporting utensils.

4:. In a water heater, the combination with an arcuate water conveying pipe whose ends face in the same direction; of two additional arcuate pipes with the ends of each extending in opposite directions, each end of the first aforesaid pipe being aligned with one end of one of the second aforesaid e pipes; two connecting pipes each in threaded connection with two of the aforesaid aligned pipe ends; a fuel burner beneaththe first pipe and a fuel burner beneath the remain ing two pipes, said fuel burners being positioned to present their flamesv to the inner sides of said pipes.

In witness whereof, I hereunto subscribe iny'name this fourth day of March A. D.,
